It is available to rPET producers and converters to help improve recycling and sustainability of PET bottles. SmartHeat RHC improves the thermal stability of PET and helps to minimize yellowing, which can help reduce the amount of toner or color required in rPET and PET bottles. Over time, as the level of SmartHeat RHC in the recycle stream begins to rise, the overall quality of rPET is improved, contributing towards increased levels of rPET content in PET bottles by addressing the root cause, rather than masking the issue.

PRODUCT BULLETIN ColorMatrix™ Amosorb™ 4020R High rPET Content Oxygen Scavenging Additive Part of the ColorMatrix™ Amosorb™ range, Amosorb 4020R is an oxygen scavenger booster specifically formulated for use with recycled PET (rPET). The EU’s directive for use of recycled PET (rPET) in bottles will increase from 25% in 2025. Brand owners would like to ensure the oxygen scavengers used in their PET bottles maintain their oxygen scavenging efficacy with the introduction of increasing levels of rPET.

PRODUCT RANGE HIGHLIGHTS Amosorb™ 4020E • Non-nylon based oxygen scavenging technology for PET • Helps to prolong the shelf life of many products in major markets Amosorb™ 100 • Non-nylon based oxygen scavenging technology for PET • Developed to meet the needs of the North American market • Featuring a special additivation package to allow for pre-consumer regrind Amosorb™ 4020G • Lower haze levels and lower impact on PET recycle stream • Non-nylon based active oxygen scavenger • PET and rPET compatible • Can be used with mono-layer and multi-layer applications Amosorb™ 4020R • Consistent performance with all levels of rPET (25%, 50% and 100%) • Improved haze and color when in combination with rPET • Flexibility on choice of rPET grade • Non-nylon based product Amosorb™ SolO2 -1 (non-carbonated/ carbonated) and SolO2 -2 (carbonated) • Nylon based oxygen scavenging technologies for PET • Active barrier effect to prevent O2 ingress • Passive barrier effect to prevent gas ingress and digress from the packaging (i.e. Targeted Solutions Avient offers oxygen scavengers that can be used with a wide variety of PET based resins and rPET grades, while being suitable to use for both mono- and multi-layer containers. The ColorMatrix™ oxygen scavenger portfolio provides advanced product protection extending the shelf life of oxygen sensitive beverages and foods packed in PET and rPET containers.

The use of typical scavenging and barrier technologies in PET, however, can be a source of contamination to rPET causing yellowing and discoloration of the recyclate over both time and multiple heat histories. Capture maintains PET clarity and allows up to 100% rPET usage to help brands achieve their goals. The technology can be used with PET or rPET bottles and is suitable for both hot-fill and aseptic filling operations.

Standard ColorMatrix toners to mask yellowing of rPET preforms are also available. PET PROCESS AIDS Challenge: Increasing rPET often creates processing challenges. SLIP AGENTS Challenge: Incorporating rPET increases cycle times.

The additive is designed for use with recycled PET (rPET) and delivers full oxygen scavenging performance with up to 100% rPET content. Brand owners and convertors alike face the challange of ensuring that the oxygen scavengers they use in their PET bottles maintain efficacy with the introduction of increasing levels of rPET. TARGET MARKET & APPLICATIONS PET and rPET rigid packaging for food & beverage products.

PET degrades and yellows at high temperatures, hence reducing the time of exposure to heat in SSP, can help to reduce the yellowing of rPET. ColorMatrix rePrize is metered into the PET stream just above the extruder feed throat using a ColorMatrix FlexCart dosing system. Melt processing of rePrize in PET blends is done at typical polyester conditions.
